A tire forming core composed of a plurality of sections the inner face of each of -which is provided with a longitudinal recess terminating in a lateral opening, the extremities of saidsections being provided with an inlet slot and a projecting lug adapted to engage the corresponding slot and lug of the adjacent section when the sections' are assembled to form an interlocking connection.

4. A tire forming core composed of a plurality of sections the inner face of each of which is provided with a longitudinal recess terminating in a lateral opening, the extremities of said sections being provided with an inlet slot and a projecting lug adapted to engage the corresponding slot and lug of the adjacent section when the sections are assembled to form an interlocking connection, and means engaging said recesses in the sections for retaining the sections in place when the core is assembled.

5. A tire forming core composed of a plurality of sections the inner face of each of which is provided with a longitudinal recess terminating in av lateral opening, the extremities of said sections being provided with an inlet slot and a projecting lug adapted to engage the corresponding slot and` lug ofthe adjacent section when the sections are assembled to form an interlocking connection, and a lookin section slidablel upon the core and provided with devices engaging the recesses of the sections for retaining .the sections in place when the core is assembled.

6. A- tire forming core collposed of a plurality of arcuate sections, each having a longitudinal recess terminating in a lateral opening, an annular locking member provided with a plurality of arms and movable upon said sections, land adjusting and securing bolts passing through said arms.

7. A tire forming core composed of a plurality of arcuate sections, each having a longitudinal recess terminating in a lateral opening, an annular locking member provided With a plurality of arms and movable upon said sections, devices carried by said arms engaging in said recesses, and bolts passing through said arms and devices carried thereby for securing the parts in position upon the sections.

8. A core for tires ymade up of a plurality of sections, a continuous locking ring, and c interengaging members carried by said locking ring and said sections, said interengaging members being of such shape that bodily rotation of said ring with relation to said members Will tighten the ring on the e sections and lock all of said sections to gcther.-
